Because mine doesn't use a hammer, it just lets the pilot volume expand slightly each shot.
Got a link?
I've still only posted one cannon here, it just does everything
It has a ball valve on the pilot line followed by a blowgun.
If you charge it up, dump the blowgun with the ball valve shut it lets out a little bit of the pilot air.
However opening the ball valve will now repressurise the space behind the blowgun and slightly drop the pilot pressure behind the QEV causing it to dump gas into the barrel until it equalises again.
To simplify it I sketched a sleeve valve pilot concept which replaced both the ball valve and blowgun while still doing the same thing (because my cannon was never meant to work like that).
Your hammer valve whacks the poppet to let out a bit of pilot gas instead.
